Installing Cooling Chassis
Correct installation of the cooling chassis is extremely im
-
portant to insure the proper operation of the unit. Install the
chassis as follows:
CAUTION
Do not pull on evaporator fan housing, control box or compressor.
Do not lift by pulling on the tubing. Tubing can crack or
bend damaging the unit.
1.
Remove outer carton and inspect for any shipping
damage. Report any found to the carrier.
2.
Check nameplate data on chassis to insure that the
correct job site distribution has been made with respect
to cooling capacities. Generally, corner rooms require
larger capacities.
3.
Remove chassis from carton by pulling evenly on
substantial portion of unit.
4.
If wall sleeve has been previously installed, remove
temporary weather panel.
5.
Check all fasteners to make certain they have not come
loose during shipment. Do not loosen bolts holding
down compressor; they are set at the factory.
6. If the Vent Door shipping screw was not previously
removed, remove it now.

Place Tinnerman clips from bag onto wall sleeve. Clips
and mounting screws are enclosed in a bag attached to
the top of the condenser coil housing.
9. If louver has not been previously installed, connect to
wall sleeve as described above.
10.
If louver is supplied by others, as illustrated in
Figure
10 on page 9
, be sure to install foam type gaskets on
all sides of the condenser coil to prevent recirculation or
bypass of condenser air.
11.
Slide chassis into wall sleeve until firmly seated against
weather seals of wall sleeve.
Figure 28: Slide chassis into wall sleeve
CAUTION
Do not push on coil surface or control box cover. Make sure the
compressor tubing does not catch when inserting chassis.

Secure chassis to wall sleeve with four (4) sheet metal
screws (2- each side), packaged with the Tinnerman clips.
